Chemical Structure

Potassium tetrachloroaurate(III) hydrate CAS 27988-75-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 395.88 g/mol gives Potassium tetrachloroaurate(III) hydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Potassium tetrachloroaurate(III) hydrate (CAS 27988-75-6) is a high-purity analytical reference standard with the molecular formula AuCl4KH2O and a molecular weight of 395.88 g/mol.

The molecular framework of Potassium tetrachloroaurate(III) hydrate (AuCl4KH2O) is characterized by a salt form, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures Potassium tetrachloroaurate(III) hydrate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
